Quiberon V is a hot, dry planet where few beings can survive a single, nine-hour day on its surface. Violent sandstorms occur at almost regular intervals and the only safe locations for settlements are underground or in one of the three calderas, known officially as VK-I, II, and III. At the equator lies an expansive cavern which scientists believe to be the remains of an underground reservoir. Surrounding the cavern are vast plains of rocky terrain known as the Skillet, site of a growing megalopolis. At night, local reptilian creatures will crawl from the cavern, where they spend the day sleeping, and warm themselves on the cooling stone and carry out their lives. The animals are blind to light but can detect variations in temperature from miles away. They will also change colors depending on their internal temperature from a blue-green coloration to a vivid red and black. Various studies have attempted to reveal the development of the peculiar species, which is unlike any other on Quiberon V, but there are few plausible theories.
